A popular Russian card game of 1 - 6 players at once. Transferrable durak option allows the defender may choose to pass the attack on clockwise around the table. In this case, the defender may only pass on the attack if he has in his hand a card of the same rank as the attacking card. To pass on the attack, he adds this card to the attacking card. The defender is now the attacker, and the player to his or her left is the defender.
